AbstractWith intensified contradiction between the rapid development of modern industry and the carrying capacity of natural environment, coordinating the relationship between economic benefits and ecological benefits is a significant issue to be solved for modern industrial engineering. This paper firstly conducts the comparative analysis between traditional and ecological industry as well as traditional and modern industrial engineering, and indicates that eco-industrial engineering is an inevitable choice for sustainable development of modern industrial engineering; Then, based on industrial ecology, environmental economics and sustainable development theory, the connotation and definition of ecoindustrial engineering are proposed, and the theoretical and practical development of the concepts of eco-industrial engineering are further investigated. Furthermore, the research subject, research content, academic system architecture and evaluation methods of eco-industrial engineering are discussed. Finally, combining the current scientific and technological development, we put forward the important scientific value and practical significance of constructing eco-industrial engineering for the utilization of these concepts.

In recent years, the central leaders and relevant ministries and commissions have issued guidelines for the development of China's industrial design, and the development of industrial design in manufacturing enterprises has attracted more attention. At present, the development level of industrial design in various regions and industries in China is uneven. No institution or organization can accurately provide nationwide survey data, and the existing regional or industry-related survey data lack uniformity and continuity, which cannot provide sufficient reference for the country to formulate relevant policies. This paper mainly describes the building of index system of industrial design and development in manufacturing enterprise. The paper builds the framework based on literature at home and abroad, two rounds of questionnaire, expert interview and field research, selects indexes through Delphi method, analytic method and frequency analysis approach and then revises index system according to the expert evaluation of regional pilot. It attempts to connect with national statistical framework, so as to grasp the problems and trends of the development of industrial design. The establishment of index system of industrial design and development in manufacturing enterprise plays an important role in the future development of China's industrial design and the formulation of economic transformation policies.

Noise pollution is exacerbated by the rapid urban development. Noise has a serious impact on both people's life and cities' ecological environment. Noise should be controlled immediately. Plants are one of the natural noise-reducing materials, which becomes increasingly important and popular. In urban landscape design, it is very important to select the plant species which have good noise reduction effect. The aim of this paper is to find out the characteristics of the plants with good noise reduction effect and apply it in urban landscape design. In this study, an experiment of sound attenuation by plants focusing on leaf vibration is carried out. This study investigates the vibration of leaves of 6 plant species in a sound field using a Keyence (IG- 1000/CCD) Laser Micrometre. The results show that the vibration amplitudes of plant leaves increase significantly by about 4-12 um after being stimulated by sound. In addition, driven by the same sound, the amplitudes of all leaves varied with the difference of leaf thickness, leaf area and leaf mass. The amplitudes of all leaves increase with the increase of leaf area and leaf mass, while decrease with the increase of leaf thickness.
